If you bought through Trip, they do no have a QR Code. At the gate entrance, show the passport booking holder and they will ask you to wait while they generate a QR Code. The place is so huge and be ready to walk about 10km if you do not want to miss any of the attractions. Kids will be tired and you can rent a stroller. The signs are properly labelled. The brochure map is in Chinese that is the downside for the foreigners. The rest is all good. Worth your money if you stay longer and complete the park. Feeding the animals need to pay a bit, and every attractions there are food trucks available, so do not worry, you wont be hungry in this park. For muslims, its tough, no halal logo for the shops. There is a cafe opposite the white tiger jumping show, no pork no lard. Or else, bring your own food/cup noodles. White tiger jumping show is a must to watch!
